Pro-Russian Hackers Claim Cyberattack on Norway
A pro-Russian hacker group called Server Killers claimed responsibility for a cyberattack that has disrupted multiple Norwegian government digital services. The attack, which began on Monday, involved denial-of-service tactics aimed at overwhelming the Norwegian Digitalization Agency’s systems. Are Kvistad, a spokesperson for Digdir, called it the largest such attack the agency has ever faced. The group said the attack was in response to Norway’s renewed security cooperation with Ukraine, including a $9.2 billion aid package announced by Prime Minister Jonas Gahr Støre.
Hackers Targeted Key Digital Services
The cyberattack targeted services that allow Norwegian citizens to use a single login across multiple public services. The hackers used denial-of-service attacks to flood Digdir’s systems with traffic, aiming to block access. Despite the disruption, Kvistad said the agency managed to keep services running “practically all the time.” The attack comes amid heightened tensions in Europe, with Russian-backed hackers accused of targeting infrastructure and public services across the continent.
Link to Norway’s Support for Ukraine
Server Killers said the attack was a declaration of cyber war on Norway following the country’s renewed security cooperation with Ukraine. On August 23, Norway announced it would provide 85 billion Norwegian crowns (about $9.2 billion) to Ukraine from next year’s budget for a third consecutive year. The two nations also agreed to expand cooperation in drone technology and other forms of modern warfare. Norwegian officials did not comment on the hackers’ claim by the time of publication.
Previous Cyberattacks Linked to Pro-Russian Groups
Server Killers has been linked to previous cyberattacks in Norway and other European countries. In 2025, Norwegian authorities said Russian hackers were likely behind suspected sabotage at a dam, where they accessed a digital system controlling a valve. In Denmark, Russian-linked groups were blamed for cyberattacks on infrastructure and websites in 2024 and 2025. Danish officials said these attacks were intended to undermine public trust and drain investigative resources.
Europe on High Alert for Russian Cyber Activity
All European countries are on high alert due to increased Russian sabotage and cyberattacks since the full-scale invasion of Ukraine in 2022. Officials say these attacks aim to spread fear, create discord, and weaken support for Ukraine. The recent Norwegian incident is part of a broader pattern of cyber aggression by Russian-backed groups. While Norway has not confirmed the hackers’ claim, the attack highlights the growing threat of cyber warfare in the region.
